CARL L. JAEGER, OF MAYWOOD, NEW JERSEY.

RECORDING DEVICE.

Specification of Letters Patent.

Patented Aug. 13, 1907.

Application filed January 16,1906. Serial No. 296,284,

To all whom fit may concern:

' Be it known that l, CARL L. JAEGER, a citizen ol the United States, and a resident of Maywood, in the county et' Bergen and State ot' New Jersey, have invented certain new and uselul Improvements in Recording Devices, of which the l'ollowing is a specification.

My invention relates to improvements in recording devices and especially to recording Compasses, such as disclosed in my prior patents 1J7i472,l24, #533,902, #556,987, #639,053, and has for its object to simplify the general construction of the apparatus therein disclosed and particularly to arrange the parts so as to permit ot the simultaneous observation oi both record sheet and compass card.

For this purpose my invention consists essentially oi a compass needle suitably mounted, and carrying a compass card and a spiral conductor; a record sheet suitably supported and visible beneath said card, means to move said record sheet, a radial conductor beneath said record sheet'` means to cause a spark to pass between said spiral conductor and said radial conductor, and a transparent cover to which said compass needle, card and spiral conductor are loosely attached and to which they may be locked when it is desired to remove or replace the record sheet.

The nature ol` my invention will be best understood in connection with the accompanying drawings in which- Figure l is a top view ot' my improved compass, showing both the compass card and the record sheet. Fig. 2 is a vertical section ol the apparatus. Fig. 3 is an enlarged sectional and plan view of the support. for the record sheet. Fig. 4 is a diagrammatic view showing the various electrical connections.

Similar characters of reference designate corresponding parts throughout the several views.v l Referring now to the drawings, l0 indicates a compass needle provided with the usual jewel bearing and mounted upon the pivot shaft ll. Carried by this needle is a trame work l2' supporting an annular compass card l3 ol' the usual type, forming with the needle l0 a compass. ltigidly secured to the arms of the frame work l2 is a conductor 14 bent in the form of an Archimede-an spiral. The pivot shaft ll is centrally mounted within an insulating shaft 15 passing through the two frame plates 16 and l7 These plates are held together by means ot' a number of posts lS and 19 and screw caps 20. Between these plates is mounted a clock mechanism, not shown, but indicated by the wheel 2l, mounted upon the driving shaft 22, which passes through and projects above the upper trame plate 16. A pinion 23 carried by the portion ol the shaft 22 above the traine plate 1G engages a gear wheel 24 keyed to the hub 25, causing it to rotate about the sleeve 26 on the insulating shaft l5. This hub 25 is constructed with a top supporting flange, as shown in Figs. 2 and 3, and which is provided with a number ol unequally spaced pins 27 which are adapted Y to secure a record sheet 2S supported by the said [lange directly below the lower edge ol' the spiral conductor i4 and concentric therewith and adapted te share the movement oi the hub 25. l prefer to space these pins unequally, as shown, so that it is impossible to incorrectly place the record sheet upon the supporting flan ge; and allowing the record sheet itself if properly graduated to indicate the time in conjunction with the usual lubbers-line or a separate indicating pointer.

Directly beneath the record sheet 2S is adjustably mounted a conductor 29 which l term the radial conductor and which is usually placed parallel to the keel and participates in the movement ol' the vessel; and is radial with respect to said compass, spiral conductor and record sheet and so placed that the record sheet is interposed between it and the spiral conductor 14 as shown in Fig. 2A The spiral conductor 14 thus crosses or intersects, during the movement oi the compass, the radial conductor 29 at various points, each point of intersection corresponding to a particular point oi the compass.

ln addition to the spiral conduct-0r 14, l have shown three other conductors, terminating in points 30, 31, and 32, placed directly above the record sheet 2S and radial conductor 29 and mounted between two insulating plates 33 and 34 and carried out of the apparatus by the wires 35, 3G, and 37 through three insulating shafts 38, 39, and 40. These points are adapted to record the time at which certain operations take place: for example to secure a record of the log, the revolutions oi the engine and any signals to which they may be connected such as a whistle, etc. A spark is caused to pass between these points or the spiral, and the radial conductor 29 when the corresponding circuit is closed and a perforation is thus made in the record sheet 28 which lies between, and a permanent record is obtained.

The posts 19 above the upper frame plate 1G carry a rim 41 to which is hinged an angle piece 42 carrying a transparent plate such as the glass plate 43 held therein by means oi the split spring-ring 44. Centrally disposed with respect to this glass plate 43 and attached to it are two metallic plates 45 and 46, the one above andthe other below the said glass plate and the lower one carrying a spring piece 47. The lower arm ol the spring piece 47 is adapted to receive the neck 48 oi' the compass bearing stud 49 thereby loosely attaching the compass needle, card and spiral conductor to the glass cover 43 but normally allowing the said stud to move ireely therein. A thumb screw 50 projecting above the glass plate and working in a thread of the bushing 51 is attached to the lower arm ol the spring 47 and as it is turned raises or lowers the said spring. The compass stud is thus also raised by the lower arm shouldering against the head of the said stud and thereby carrying it and the compass needle.l0, card 13 and spiral 14 ofi their supporting pivot shaft 11 raising them until the head oi the bearing stud 49 is held against the block 52 fastened to the upper and fixed arm oi the spring 47. The compass needle 10, card 13, and spiral 14 thus become held against the glass cover 43 and the whole may be turned up with the cover allowing the insertion or the replacing of the record sheet. The cover may then be turned down, the thumb screw turned back releasing the compass needle, card and spiral, which again assume their proper positions. In place of the means shown to lock the said compass needle, card and spiral to the cover I may of course use other means such as means to automatically lock the compass needle, card and spiral upon lifting the cover, and I do not wish to restrict myself to any particular means.

In Fig. 4 I have shown diagrammatically the electrical connections. Current is derived from a dynamo 53 through the mains 54 and 55. An electro-magnet 5G is shunted across these mains as shown and is adapted to automatically throw into circuit the emergency battery 57, should the circuit from the dynamo fail. Four spark coils 5S, 59, 60 and 61 are shown controlling respectively the compass record, the signal record, the revolution record, and the log record. Into one of the mains 62 or 63 leading to the spark coil 58 I have indicated a time-controlled circuit closer 64 inserted. This device is adapted to periodically close the primary circuit ot the spa-rk coil and thereby cause a spark to periodically pass between the spiral conductor 14 and the radial conductor 29 puncturing the record sheet 28 and making a permanent record thereon. I prefer to employ the above circuit closer and record a series oi perforations. The other primary coils are respectively connected to and controlled by signals, revolution counter and a log which are adapted to close the said primary circuits. As soon as these primary circuits are closed, a current is induced in the correspond'- ing secondaries and causes a spark to jump between the radial conductor and the respective points 30, 31, and 32, and thereby puncture the record sheet 28. It is evident that a similar recording device may likewise be employed to record the movements of a magnetic dipping needle or the movements of other rotatable indicators, provided slight structural changes be made. Further, by Calibrating the record sheet also upon the reverse side and properly indicating the times, this sheet may serve as a valuable aid in determining the return course oi a ship.
